Question 52826: How do you graph volume? I have this equation that I received help in obtaining the answer but I don't know how to graph it. V(x) = 4x^3 - 28x^ + 48x I have graph 4.0.1 but I can't figure out how to graph in it.

The graph of your equation is: graph%28300%2C300%2C-5%2C5%2C-50%2C50%2C4x%5E3-28x%5E2%2B48x%29. Note you can factor out 4x to get 4x%28x%5E2-7x%2B12%29, which further factors to 4x%28x-3%29%28x-4%29. Taking those three factors shows us that the graph should cross the x-axis when x=0, x=3, and x=4. All that means when x has those values, y is 0.
